Tuner (radio)

A tuner is a subsystem that receives radio frequency (RF) transmissions like radio broadcasts and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output. Broadcast FM/AM transmissions usually feed this intermediate frequency (IF) directly into a demodulator that convert the radio signal into audio-frequency signals that can be fed into an amplifier to drive a loudspeaker. More complex transmissions like PAL/NTSC (TV), DAB (digital radio), DVB-T/DVB-S/DVB-C (digital TV) etc. uses a wider frequency bandwidth, often with several subcarriers. These are transmitted inside the receiver as an intermediate frequency (IF). The next step is usually either to process subcarriers like real radio transmissions or to sample the whole bandwidth with A/D at a rate faster than the nyquist rate that is at least 2 times the IF frequency.

The term tuner can also refer to a radio receiver or standalone audio component that are part of an audio system, to be connected to a separate amplifier. The verb "tuning" in radio contexts means adjusting the radio receiver to receive the desired radio signal carrier frequency that a particular radio station uses.

Freak Power

Freak Power was a band founded by Norman Cook (later to become known as Fatboy Slim), Ashley Slater (the trombonist with the anarchic British jazz big band Loose Tubes), and Jesse Graham, also known as "the Bass Cadet." Their music was a mix of acid jazz with funk and soul, along with trip hop.

Discography

The single "Turn On, Tune In, Cop Out" was a minor hit in UK Singles Chart when originally released in 1993. There was renewed interest in the track after TV exposure in the 1995 Levi's jeans television advert "Taxi" directed by Baillie Walsh. The band released two albums: Drive Thru Booty in 1994 and More Of Everything For Everybody in 1996. The debut album featured the hit singles "Turn On, Tune In, Cop Out" and "Rush" released on 4th and Broadway. The title of the song is a play on Timothy Leary's "Turn on, tune in, drop out".

"Song #6" from the band's follow-up album was featured in the 2004 movie Code 46.
